Integrated Vehicle Control Unit for Reliable Emergency Call Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency call systems in vehicles are prone to incorrect signal transmission due to malfunctions in control units, and may fail to transmit signals during actual accidents if the central gateway is damaged, leading to unreliable emergency call functions.
Innovation Solution
An integrated control unit within the vehicle monitors sensor signals to determine airbag deployment and automatically requests an emergency call, directly transmitting to an emergency call unit without relying on the central gateway, thereby reducing errors and ensuring reliable communication with the emergency rescue center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the emergency call system uses a separate central gateway and airbag control unit to transmit signals, then the system architecture is modular and easier to manufacture, but signal transmission reliability deteriorates due to potential malfunctions in intermediate control units
Solution Approach 1:
The patent combines the airbag control unit and emergency call unit into a single integrated control unit. This merging eliminates the central gateway as an intermediate component, allowing the emergency call unit to directly receive sensor signals and airbag deployment status from the accident determination unit within the same integrated controller, thereby ensuring reliable signal transmission without interference from separate control units.
2Reliability
If the system uses multiple separate control units (sensor unit, airbag control unit, central gateway, eCall unit), then the system is easier to manufacture and maintain, but the number of potential failure points increases
Solution Approach 1:
The patent integrates the airbag control unit and emergency call unit into one unified control unit, reducing the total number of separate components. This integration maintains ease of manufacture by consolidating control functions while improving reliability by eliminating the central gateway and reducing the number of communication interfaces between separate units, thereby minimizing potential failure points.
3Speed
If the central gateway is used as an intermediate transmitter for emergency call signals, then the system architecture is more distributed and fault-tolerant, but signal transmission speed and directness deteriorate
Solution Approach 1:
The patent extracts the emergency call function from the distributed architecture that requires the central gateway, and integrates it directly into the airbag control unit. This extraction eliminates the intermediate transmission step through the central gateway, enabling direct signal transmission from the accident determination unit to the emergency call unit within the same integrated controller, thereby improving transmission speed and simplifying the communication architecture.

AI summary
The present disclosure relates to a vehicle and a method for controlling an emergency call therefor, and more particularly, to a vehicle capable of performing a more stable and reliable emergency call and a method for controlling an emergency call therefor. The method for controlling an emergency call for a vehicle according to an embodiment includes monitoring a sensor signal in an accident determination unit of a control unit; determining whether or not an airbag is deployed based on the sensor signal in the accident determination unit; requesting an automatic emergency call from the accident determination unit to an emergency call unit of the control unit if the airbag is deployed as a result of the determination; and attempting to transmit a call to an emergency rescue center in response to the request from the emergency call unit.
